The last few pictures show them adhering after 6 months on a sample piece of nylon material.that patch has been in place for over 2 years.However, they do struggle with highly waterproof fabrics (i.e. where the water bubbles on contact with the fabric and doesn& 39;t soak in).The intent of the product is to offer a cheap alternative to replacing a jacket (i.e. ~3 as a fix, rather than 50 - 200 on a new jacket or gilet.My offering is to provide a number of colours for a cheap price and to offer a fix for down jackets.
